Abstract

The current study aimed to test the applicability of the modified receptive field (MRF) theory (Tydgat & Grainger, 2009) with English native speakers (Experiment 1) and Sinhalese native speakers (Experiment 2), who were skilled readers of both Sinhala and Roman scripts. A two-alternative forced choice (2AFC) procedure to measure identification accuracy for all positions in a string of five characters, which consisted of Roman script letters, Sinhala letters or symbols was conducted. For Roman script, the English and Sinhalese speakers displayed analogous results as in previous studies for Roman letters and symbols (i.e., an initial letter advantage and W-shaped function for Roman letters and a Λ-shaped function for symbols). In contrast for Sinhala script, the Sinhalese speakers displayed a strong linear function with accuracy for letter positions 1, 2 and 3 similarly advantaged. We propose that this characteristic pattern for Sinhala script has developed as a specialised adaptive mechanism to optimise the processing of letters when reading in this distinctive script.
